What is the exact value of sin 75?

Answer #1:

The exact value is (square root of 6 + square root of 2) / 4

===========================

Answer #2:

I don't think so.

The sine of almost all angles is an irrational number. 75 degrees is one of them.

That means its sine can never be exactly written with numbers.

The value given in Answer #1 is greater than ' 1 ', and we know that no sine can

have that value.
